MACHINE FOR FASTENING CORNERS OF PASTEBOARD BOXES WITH METAL CLIPS.

SPECIFICATION forming part of Letters Patent No. 458,510, dated August25, 1891.

Application filed March 18, 1891. Serial No. 385,522. (No model.)

To all whom it may concern.-

Be it known that I, JOSEF WEIL, manufacturer, a subject of the Emperorof Austria, residing at Weinhaus, near Vienna, in the Province of LowerAustria, in the Empire of Austria-Hungary, have invented certain new andusefullmprovements in Machines for Fastening the Corners of Paper orPasteboard Boxes and the Like by Means of Metallic Angles 5 and I dohereby declare the following to bea full, clear, and exact descriptionof the invention, such as will enable others skilledin the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The invention relates to the manufacture of boxes, and has for itsobject to provide means whereby the meeting edges of the walls of suchboxes may be securely fastened together and strengthened.

The invention consists in means for fastening together the meeting edgesof the walls of boxes constructed of a light material as, for instance,paper or pasteboard boxes or boxes constructed of thin veneer-as willnow be fully described, and shown in the accompanying drawings, inwhich-- Figure 1 is a sectional side elevation, and Fig. 2 a like frontelevation, of a machine for fastening together and strengthening themeeting edges of the walls of boxes or the corners thereof. Fig. 3 is avertical longitudinal section of a box having its upper corners securedby means of a metallic fastener.

Fig. 4 is a perspective view of part of a box,

showing the fastener applied to one corner thereof, and Figs. 5 and 6are like views of two forms of metallic fasteners.

Like symbols indicate like parts wherever such may occur in the abovefigures of draw- The co-operating devices of the machine are supportedfrom a suitable table T, on the cross-braces b of which are securedbearings h for a foot-lever h, that is connected by a link g to a rod g,pivoted to a lever f, that carries a weight f adjustable on said leverby means of a set-bolt f The lever fis fulcrumed at f to a tubularoverhanging arm a of the machine-frame A, which is bolted to table T,and said tu ular overhanging arm serves as a bearing fof' aplunger-bar19, whose upper enlarged end or head b is forked, said forked endstraddling the lever f. A spring (I on plunger-bar b in the upperenlarged por-' latter again released, so that after each downwardmovement of the lever and plunger they are again returned to theirnormal positions by the springs 61 and 0.

Below the plunger-bar bearing the machineframe is provided with ahorizontal opening that in cross-section corresponds with the likesection of an anvil k, one half of which is or may be semi cylindricaland the other prismatic, as shown at Figs. 1 and 2, so as to conform tothe angles of a box. The anvil has upon each of its inclined faces aprojecting boss or teat 70 and said anvil is adjustable in its bearingby means of a set-screw Z, so that fasteners of difierent widths may beapplied. The plunger-bar b has its lower end socketed, and in saidsocket is seated a plunger 0 and secured in position by means of a setscrew or bolt 0'. The plunger 0 has a V-shaped recess in its lower facecorresponding with the prism-shaped portion of the an vil lo, and ineach of the inclinedfaces of said recess is formed a concavity 0 that isen tered by the bosses or teats k of the anvil or that registertherewith whenever the plunger is brought down onto the said anvil.

The fasteners m are substantially V-shaped in section and right angular.They are constructed of sheet metal and in their application to thecorners of a box they are placed in proper position. The box is thenplaced metallic fastener is indented on one side and caused to bulge onthe other side of the material, securely grasping the latter in the indentations and securely locking the fastener thereto. The metallicfasteners m not only securely fasten the walls of the box at thecorners, but also strengthen the box materially.

If desired, the upper edges of both ends or sides of a box may beprovided with a metallic binding by means of a fastener M of suitableconstruction and shown in Fig. 6, or the upper edges of all four sidesmay be so bound, if desired, and as will be readily understood.

It will be understood that the concavities c in the plunger may beformed in the anvil and the plunger provided with teats k for thepurpose stated.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is-

1. In a machine for fastening together and strengthening the corners ofboxes, the combination, with an anvil having a substantially V-shapedoperating-face provided with bosses or teats, of a plunger provided withaV-shaped recess adapted to fit the operative face of the anvil and withconcavities adapted to register with the bosses or teats on the anvil,apressurelever having bearing on the plunger, a spring acting on theplunger to move the same upwardly, a foot-lever connected with the pressure-lever, and a spring operating on the lastnamed lever to move thesame upwardly, for the purpose set forth.

2. In a machine for fastening together and strengthening the corners ofboxes, the combination, with the anvil is, adjustable in its bearings,the plunger 1), provided with a forked head 6, and a spring operating onsaid plunger to move the same upwardly, of the lever f, carrying anadjustable weight f and having hearings in the forkedv head of theplunger, the foot-lever h, the rod g, link g, connecting said foot-leverwith lever f, and a spring operating to move the last-named leverupwardly, as described,for the purpose set forth.

In testimony whereof I atlix my signature in presence of two witnesses.

JOSEF WEIL.
